• White Blood Cells fight harmful bacteria, viruses and fungi and help to remove them from the body.
• Red Blood Cells transport oxygen from the lungs to the other parts of the body and carry carbon dioxide back to the lungs.
• Platelets help in the clotting process by gathering at a bleeding site and clumping together to form a plug that helps seal the blood vessel. At the same time, they release substances that help promote further clotting.
• Plasma is the liquid component of blood that suspends the components. It contains the protein albumin that keeps liquid from leaking out of blood vessels and into tissues. Plasma also prevents blood vessels from collapsing and clogging and helps maintain blood pressure and circulation throughout the body simply by filling blood vessels and flowing through them continuously. Plasma circulation also plays a role in regulating body temperature by carrying heat generated in core body tissues through areas that lose heat more readily, such as the arms, legs, and head.
